Antifreeze is used in solar water heating systems as a heat transfer fluid, providing protection from freezing, and damage to the system, in colder climates. But beware! Don’t try and add or change it in your solar water heating system yourself – these systems are pressurized and any maintenance is best left to the professionals.
In the case of the closed-loop solar heating system, the HTF is typically a mixture of water and propylene glycol. The process of filling the plumbing system with this antifreeze while purging all the air out must be done systematically and in the right order. This is known as “charging” the system.
Glycol is now pumped out of the bucket, filling the solar collectors from the bottom to the top. Air in the collectors and the pipe is pushed out the purge hose back into the top of the bucket by the charge pump. At first, air returns into the bucket and then glycol mixture with air and foam, which can be very hot.
Recommended procedures: A utility pump and three high-temperature flexible hoses are required to connect to the fill and purge ports. This pump must be capable of lifting the glycol mixture from the mechanical room up to the top of the solar collectors. Pumps are commonly used for this purpose with output pressure ratings of 30 to 60 psi.
Recommended procedures: The following steps are recommended before charging the system with glycol mixture. Pressure-test the solar plumbing loop with compressed air to twice the normal operating pressure. Use the ball valves on float vents and expansion tanks to seal off these components during the test.
Use the proper pressure relief (PR) valves in the solar glycol loop with the right pressure rating and no temperature probe. Install a metal blow-off tube from the PR valve into a metal collection tank. Make sure diaphragm expansion tanks, air vents and all other components exposed to high-temperature glycol are rated for these extremes.
